Example-1: Iterate the loop for a fixed number of times Create a bash file named while1.sh with the following content. Here, the loop will iterate 5 times and print the counter value in each iteration. #!/bin/bash # Initialize the counter n=1 # Iterate the loop for 5 times while ...
while loop Flowchart Syntax while(test condition){ //code to be executed } If the test condition inside the () becomes true, the body of the loop executes else loop terminates without execution. The process repeats until the test condition becomes false. Example: while loop in C // ...
Now that you’ve seen how a while loop works – feel free to explore using it for a variety of programs as required. If you’re aware of clever trick using the while loop or have trouble using it in your program, let me know in the comments below....
We can use abreak statementinside awhileloop to terminate the loop immediately without checking the test condition. For example, while True: user_input = input('Enter your name: ') # terminate the loop when user enters end if user_input == 'end': print(f'The loop is ended') break pr...
for(i in 1:5) { # Head of for-loop if(i < 4 & i %in% seq(2, 10, 2)) { # Combine two if-conditions print(i) # Some output } } # [1] 2The output is the same.Note that we could apply the same logic within other types of loops such as repeat-loops or while-loops....
for loop in C 1. while Loop in C While loop executes the code until the condition is false. Syntax: while(condition){ //code } Example: #include<stdio.h> void main() { int i = 20; while( i <=20 ) { printf ("%d " , i )...
While condition: expression(block of code) Unlike thefor loop, thewhile loopdoesn’t iterate over a sequence. It uses the comparison operators and booleans for its condition. Let’s look at some examples to better understand how it is used. ...
You'll also learn the difference between using a while loop and a for loop. Also the topic of nested loops After, you'll see how you can use the break and continue keywords. The difference between the xrange() and range() functions While Loop The while loop is one of the first loop...
Example 2: Nesting for-Loop in while-Loop It is also possible to nest differenttypes of loops. Example 2 explains how to nest a for-loop into awhile-loop. First, we have to create a data object containing our running index: Then, we can run our nested while- and for-loops as shown...
Break statement is used for jumping out of the innermost looping (while,do-while and for loop) that encloses it. 5. Awk Break Example: Awk Script to go through only 10 iteration $ awk 'BEGIN{while(1) print "forever"}' The above awk while loop prints the string “forever” forever, ...
